revisions number when not.

  $ hg help topics
  hg topics [TOPIC]
  
  View current topic, set current topic, change topic for a set of revisions, or
  see all topics.
  
      Clear topic on existing topiced revisions:
  
        hg topic --rev <related revset> --clear
  
      Change topic on some revisions:
  
        hg topic <newtopicname> --rev <related revset>
  
      Clear current topic:
  
        hg topic --clear
  
      Set current topic:
  
        hg topic <topicname>
  
      List of topics:
  
        hg topics
  
      List of topics with their last touched time sorted according to it:
  
        hg topic --age
  
      The active topic (if any) will be prepended with a "*".
  
      The '--current' flag helps to take active topic into account. For example,
      if you want to set the topic on all the draft changesets to the active
      topic, you can do: 'hg topic -r "draft()" --current'
  
      The --verbose version of this command display various information on the
      state of each topic.
  
  options ([+] can be repeated):
  
      --clear       clear active topic if any
   -r --rev REV [+] revset of existing revisions
   -l --list        show the stack of changeset in the topic
      --age         show when you last touched the topics
      --current     display the current topic only
  
  (some details hidden, use --verbose to show complete help)
